Minor changes may be made in the invention without departing from the spirit and scope thereof as claimed. 1

What is claimed as new is Y 1. In combination, a drive shaft, a hollow casing embodying a pair of relatively fixed separable cylindrical sections having the opposite ends thereof internally provided with annular rabbets, gearing connections between the shaft and the casing, a sectional roller cage comprising apair of central rings rotatably mounted in the mating rabbets of adjacent ends of the casing sections and further rings seated in the rabbets of the outer ends of said casing sections, longitudinal pins snugly fitted in alined openings in the cage rings for main taining the same operatively spaced in predetermined relative relation, means for securing the cage to the casing sections so as to rotate with the'latter but with limit d. circumferential movement relative thereto, said cage rings being provided with openings, rollers journaled in said openings and extending across the spaces between the rings, and cylindrical clutch drumshaving their outer peripheries rotat-ably snugly fitted in the casing members with their peripheries operatively associated with the rollers, said casing sections having inner longitudinal grooves with inclined inner walls for causing wedging of the rollers in contact with the peri )heries of said clutch drums upon relative iiiovement between the sections of the roller cage and between one cage section and its casing section.

:2. In combination, a drive shaft, a hollow casing embodying a pair of relatively fixed separable cylindrical sections having the opposite ends thereof internally provided with annular rabbets, gearing connections between the shaft and the casing, a sectional roller cage comprising a pair of central rings rotatably mounted in the mat rabbets of adjacent ends of the casing sections and further rings seated in the rabbets of the outer ends of said casing sections, longitudinal pins snugly fitted in alined openings in the cage rings for main taining the same operatively spaced in predetermined relative relation, means for securing the cage to the casing sections so as to rotate with the latter but with limited eircnmferential movement relative thereto, said cage rings being provided with openings, rollers journaled in said openings and extending across the spaces between the rings, cylindrical clutch drums having their outer peripheries rotatably snugly fitted in the casing members with their peripheries operatively associated with the rollers, said casing sections having inner longitudinal grooves with inclined inner walls for caus ing wedging of the rollers in contact with the peripheries of said clutch drums upon relative movement between the sections of the roller cage and between one cage secseparable cylindrical sections having the opposite ends thereof internally provided with annular rabbets, gearing connections between the shaft and' the casing, a sectional roller cage comprising a pair of central rings rotatably mountcd in the mating rabbets of adjacent ends of the casing sections and. further rings seated in the rabbets of the outer ends of said casing sections, longitudinal pins snugly fitted in alined openings in the cage rings for maintaining the same operatively spaced in predetermined relative relation, means for securing the cage to the casing sections so as to rotate with the latter but with limited circumferential movement relative thereto, said cage rings being provided with openings, rollers journaled in said openings and extending across the spaces between the rings, cylindrical clutch drums having their outer peripheries rotatably snugly fitted in the casing members with their peripheries operatively associated with the rollers, said casing sections having inner longitudinal grooves with inclined inner walls for causing wedging of the rollers in contact with the peripheries of said clutch drums upon relative movement between the sections of the roller cage and between one cage section and its casing section, the means for retaining the casing and roller cage against unlimited relative rotation embodying a plurality of longitudinal bolts extending through openings in the walls of the casing sections,and the cage rings being provided with peripheral notches for loose reception of portions of said bolts.

4-. In combination, a drive shaft, a hollow casing embodying a pair of relatively fixed separable cylindrical sections having the opposite ends thereof internally provided with annular rabbets, gearing connections between the shaft and the casing, a sectional roller cage comprising a pair of central rings rotatably mounted in the mating rabbets of adjacent ends of the casing sections and further rings seated in the rabbets of the outer ends of said casing sections, longitir dinal pins snugly fitted in alined openings in the cage rings for maintaining the same operatively spaced in predetermined relative relation, means for securing the cage to the casing sections so as to rotate with the latter but with limited circumferential movement relative thereto, said cage rings being provided with openings, rollers journaled in said openings and extending across the spaces between the rings, cylindrical clutch drums having their outer peripheries rotatahly snugly fitted in, the casing members with their peripheries operatively associated with the rollers, said casing sections'having inner longitudinal grooves with inclined inner walls for causing wedging ot the rollersin contact with the peripheries of said clutch drums upon reljative movement between thesectiohs of the roller cage and between one cage section and its casing section, and means to yieldingly place the roller cage sections in frictional connection with the peripheries of said clutch. drums.

5. In combination, a drive shaft, a hollow casing embodying a pair of relatively fixed separable cylindrical sections having the opposite ends thereof internally provided with annular. rahbets, gearing connections hetween the shaft and the casing, a sectional roller cage comprising a pair of. central rings rotatably mounted in the'mating rabbets of adjacentends of the casing sections and further rings seated in the rabbets ot the outer ends of said casing sections, longitudinal pins snugly fitted in alined openings in thecage rings for maintaining the same op'eratively spaced in predetermined relative relation, means for securing the cage to the casing sections so as to rotate with the latter but with limited circumferential movement relative thereto, said cage rings bein provided with openings, rollers journa ed in said openings and extending across the spaces between the rings, cylindrical clutch drums having their outer peripheries rota tably snugly fitted in the casing members with their peripheries operatively associated yieldable means embodying spring pressed.

radially movable plungers urged inwardlyof and carried by the cage rings, one spring pressed plunger being arranged betweeneach pair of rollers.

In testimony whereof I affix my signature.
